Hey guys, I have a question about an icloud and find my iphone service. About 4 years ago (late 2011/ early 2012) I sold Iphone. I was pretty sure that while selling it I wiped the device until I recently saw this device in find my iphone website as offline. I checked in the icloud.com settings, and appleid website and did not see this device in any of them except the find my iphone site. I am just getting a little worried whether I wiped the device, or accidentally left it signed on. Has anyone encountered with this problem, or what can be the reason I see the device under find my iphone? Could that be something else rather than that I left it signed on? I appreciate your help.
